BLP-1.9+

Overview

The Mini-Circuits BLP-1.9+ is a lumped LC low-pass filter designed for signal conditioning applications within the DC to 1.9 MHz frequency range. It features a nominal impedance of 50 Ohms and utilizes BNC connectors for inline integration. The component operates reliably across an extended temperature spectrum, supporting minimum working temperatures of -55°C and maximum working temperatures of +100°C. Housed in the FF55 package, this filter provides essential frequency management for electronic systems requiring precise low-frequency signal passage while attenuating higher frequencies.

Feature Summary

• Lumped LC architecture ensures stable low-pass filtering characteristics
• BNC connector interface facilitates direct inline circuit integration
• Extended operational temperature range supports diverse environmental conditions

Applications

• Signal conditioning in measurement instrumentation

Procurement Notes

Verify the specific datasheet revision when sourcing, as electrical specifications may undergo updates. Confirm that the BNC connector type matches your system requirements. Ensure the operating environment remains within the specified -55°C to +100°C range to maintain performance integrity. Cross-reference the part number suffix with official documentation to confirm compatibility with existing designs.

Selection Notes

Select this component when a fixed cutoff near 1.9 MHz is required for 50-ohm systems. The BLP-1.9+ is suitable for applications demanding robust signal integrity at low frequencies. Consider the physical dimensions of the FF55 package during layout planning. Evaluate thermal constraints to ensure operation stays within the rated temperature limits for long-term reliability.
